United States Antimony Corp (NYSEAMERICAN: UAMY) revealed that it had fired its Mexican smelting plant back up in an SEC filing on Monday. The facility had been shut down since March last year.
The decision was inspired by the record-high price of antimony, which is largely attributable to China’s decision to ban exporting the commodity into the U.S. at the end of 2024. This spike caused US Antimony’s annual revenue to increase by 72 per cent last year, driven by a 24 per cent increase in antimony sales volume.
“The first load of antimony has now been trucked to our Madero Smelter and is being processed beginning today,” the critical mineral processing specialist specified in its Form 8-K report. “It is the company’s goal to be producing approximately 200 tons per month from Madero prior to year-end 2025.”
A second ore shipment will be refined in the immediate future and a third is currently on route to Mexico.
US Antimony focuses on processing the critical mineral and has not been involved with the mining process since the 1980s. It primarily sources ore from suppliers in Mexico, Australia and Thailand.
At the moment, US Antimony is the only American producer of antimony products like oxide, metal and trisulfide. Its smelters in Thompson Falls, Montana and the Mexican state of Coahuila are the only in operation within North America. There are no antimony mines of scale in production within the U.S.
To remedy domestic supply concerns, investors and government military stakeholders have been trying to fast-track production at the Stibnite Gold Project in Idaho run by Perpetua Resources Corp. (TSE: PPTA) (NASDAQ: PPTA). The White House just gave the development-stage site a new priority designation.
They have also been paying more attention to promising early-stage antimony operations like NevGold Corp‘s (CVE: NAU) (OTCMKTS: NAUFF) (FRA: 5E50) Limousine Butte project in Nevada.
Over 60 per cent of the world’s antimony ore supply is currently controlled by China and Russia.
